[0019] The present invention will be described in further detail below with reference to the accompanying drawings.

[0020] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] In addition, the terms "horizontal" and "vertical" do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", not that the structure must be completely horizontal, but can be slightly tilted.

[0022] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] Embodiment, a kind of impurity removal device for tea production and processing, such as Figures 1 to 3As shown, the tea screening machine 1 includes a tea screening machine 1, which is a shaking screening machine. The shaking screening machine is provided with a feed port 11 at one end away from the first conveying mechanism 2. Of course, the tea screening machine 1 can also be a round screening machine to screen out impurities smaller than the tea leaves. Tea leaves can be put into the feed port 11 manually or conveyed by a conveyor. The discharge port of the tea screening machine 1 is provided with a first conveying mechanism 2, and the other end of the first conveying mechanism 2 is provided with a second conveying mechanism 3. The first conveying mechanism 2 and the second conveying mechanism 3 are both vibrating conveyors. Of course, the first conveying mechanism 2 and the second conveying mechanism 3 can also be other types such as belt conveyors, but the vibrating conveyor can make the tea leaves evenly dispersed during transportation, which is convenient for subsequent operations. A receiving trough 4 is provided below the first and second conveyor mechanisms 2 and 3. The second conveyor mechanism 3 is located below the first conveyor mechanism 2. An air outlet duct 5 is provided at the lower end of the first conveyor mechanism 2. The air outlet duct 5 has multiple air outlets 51, which face horizontally toward one side of the second conveyor mechanism 3. A protective cover 6 is provided at the upper end of the second conveyor mechanism 3 and between the first and second conveyor mechanisms 2 and 3. A first suction hood 71 is provided above the first and second conveyor mechanisms 2 and 3. After passing through the tea screening machine 1, the tea leaves fall onto the first conveyor mechanism 2. The first conveyor mechanism 2 evenly disperses the tea leaves before they fall. During the falling process, the tea leaves are blown by the air outlets 51 onto the second conveyor mechanism 3. Impurities heavier than the tea leaves, such as pebbles, metal impurities, and insects, fall into the receiving trough 4. Impurities lighter than the tea leaves, such as hair, dust, plastic rope, and grass, are sucked away by the first suction hood 71.

[0024] The first suction hood 71 is connected to a first suction pipe 72, which is connected to a collection tank 73. The lower end of the collection tank 73 is detachably connected to a collection bucket 74. A second suction pipe 75 is connected to the upper end of the collection tank 73. A filter 76 is installed at the junction of the second suction pipe 75 and the collection tank 73. The end of the second suction pipe 75 away from the collection tank 73 is connected to a fan 77, which is connected to the air outlet pipe 5. The first suction hood 71 draws impurities into the collection tank 73, which ultimately fall into the collection bucket 74 for easy disposal. The lower end of the collection tank 73 is connected to a flexible pipe 79, which is detachably connected to the collection bucket 74, facilitating installation of the collection bucket 74.

[0025] The second feed mechanism is equipped with a second suction hood 78, which is connected to the first suction pipe 72. The second feed mechanism is also equipped with an electromagnet 8, which is located on a side of the second feed mechanism away from the first feed mechanism. This second suction hood 78 cleans the tea leaves once more, and the electromagnet 8 absorbs iron impurities, particularly thin iron wires. Its location also facilitates cleaning.

[0026] Instructions for use: Tea leaves are fed into the tea sifter 1 through the feed inlet 11. The screen size of the tea sifter 1 should be selected according to the size of the tea leaves. The speed of the first conveyor mechanism 2 should be higher than the discharge speed of the tea sifter 1 to disperse the tea leaves. When the air outlet duct 5 is in operation, the wind speed should be selected appropriately according to the weight of the tea leaves. Some tea leaves will also remain in the receiving trough 4 and require manual screening. After the tea leaves have been processed by this device, manual screening is still required to further preserve the quality of the tea leaves.

[0027] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
